Hana ʻia ʻo Chrome corundum (ʻike pū ʻia ʻo corundum ʻulaʻula) e ka hopena kemika o ka metallurgical chrome-green a me ka alumina ʻenehana ma ke kiʻekiʻe wela ma luna o 2000 degere.Hoʻohui ʻia kekahi nui o ka chromium oxide i ka wā o ka hoʻoheheʻe ʻana, ʻo ia ka poni māmā a i ʻole ka rose.
ʻOi aku ka Chromium corundum i ka hana holoʻokoʻa e like me ka paʻakikī kiʻekiʻe, ka paʻakikī kiʻekiʻe, ka maʻemaʻe kiʻekiʻe, ka hoʻomaʻamaʻa ponoʻī maikaʻi loa, ka hiki ke wili ikaika, ka hana haʻahaʻa wela, ka hana kiʻekiʻe, ka waikawa a me ke kūpaʻa alkali, ke kūpaʻa wela kiʻekiʻe, a me ke kūpaʻa wela maikaʻi.
ʻO ka hoʻohui ʻana o ka mea kemika Cr i ka chrome corundum e hoʻomaikaʻi i ka paʻakikī o kāna mau mea hana abrasive.Ua like ia me ka corundum keʻokeʻo i ka paʻakikī akā ʻoi aku ka kiʻekiʻe o ka paʻakikī.ʻO nā mea hana abrasive i hana ʻia me ka chrome corundum he paʻa maikaʻi a me ka hopena kiʻekiʻe.Hoʻohana nui ʻia ia i ka abrading, grinding, polishing, precisely casting sand, spraying materials, chemical catalyst carrier, special ceramics a pēlā aku.Loaʻa i nā māla kūpono: nā mea hana ana, nā ʻāpana mīkini, nā ʻāpana mea kani, ka wili pololei ʻana i ka hana ʻana a me ke ʻano hoʻohālike.
ʻO ka chrome corundum he viscosity kiʻekiʻe a me ka permeability maikaʻi ma muli o ka mea aniani i loko o ka chromium oxide, hiki ke pale nui i ka erosion a me ke komo ʻana o ka molten slag.Hoʻohana nui ʻia ia i nā kula wela kiʻekiʻe me ke kaiapuni koʻikoʻi, me nā kapuahi metallurgy non-ferrous, nā kapuahi hoʻoheheʻe aniani, nā reactors ʻeleʻele kalapona, nā ʻōpala ʻōpala a me nā castables refractory.
